Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build.

Mainmark’s UK team has done a great job remediating this London home suffering significant cracking due to subsidence. Thanks to renowned property expert and TV presenter Sarah Beeny for filming and sharing this project.

Although buildings might appear to be static structures, they are constantly moving, affected by even the minutest vibration of someone walking past. What if we could record these vibrations to develop a detailed structural analysis of a building?

Mainmark has a wealth of exprience in its team, including Dr Phil Irwin, Area Manager for Victoria and Tasmania, who has a PhD in Earth Sciences and is a qualified geologist.

Mainmark: With unique climates and landscapes, homes in Australia and New Zealand face diverse ground conditions that can cause subsidence, affect building foundations and result in structural issues. While most issues are due to unstable ground, extreme weather conditions including drought and floods can be common contributors to subsidence. Other factors such as leaking pipes or inferior concrete foundations can also be a cause.

Mainmark: Last year, Mainmark announced it was among only a handful of organisations in our industry to hold a 2015 ISO certification for Environmental Management and Quality Management. This is a significant achievement and demonstrates Mainmark’s commitment to complying not only with Australian Standards, but also those recognised internationally.

Mainmark recently delivered an engineered solution to solve a sinkhole problem in Sydney.

Did you know that cracking walls and uneven floors in homes are usually symptoms of a deeper, structural problem? For homeowners, regardless of where they live, identifying structural issues early and addressing them in the right way is vital. Here’s a tip: understanding the soils beneath your home can be the key.

Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build.

Retaining walls are an increasing feature of construction sites as sky high land prices add pressure to maximise the potential returns from each build. Construction companies look to utilise every inch of land when planning new developments, and many projects require high retaining walls to achieve bigger results.

When Offset Developments, a residential building company based in Christchurch, began construction on a four-unit complex in Christchurch, it encountered a significant challenge when it came to laying the foundations. The water table was only 1.2m below the surface, contributing to the very soft ground conditions. After receiving a geotechnical report, the company was advised it needed to place a raft under the slab to protect the site from possible subsidence, soil liquefaction or other issues that may arise due to the weaknesses of the ground.
